Abstract

PURPOSE:To record one line at a high speed, by a system wherein a thermal head is divided into a predetermined number of blocks, and a number of the blocks are simultaneously energized so that the sum total of the numbers of recording dots in the blocks being energized is in a predetermined range. CONSTITUTION:A thermal head is divided into blocks #1-#N, the number of recording dots energized in each of the blocks is counted, and a number of the blocks are simultaneously energized collectively so that the sum total of the numbers of the recording dots energized does not exceed a predetermined value (100%). Thus, the number of energization sections D1, D2,...Dn for the blocks #1-#N can be set to be smaller than the number N of the blocks into which the thermal head is divided, and accordingly, recording one line by the thermal head can be performed at a high speed. In addition, since the ratio of the number of recording dots simultaneously energized to the number of the recording dots capable of being simultaneously energized will not exceed 100% even when simultaneously energizing some of the blocks, there is no need for increasing the electric current capacity of a driver for the thermal head, and the thermal head can be inexpensively constructed.
